Sika® Injection AC-20

Accelerator for Sika® Injection-201 CE and Sika® Injection-203

Sika® Injection AC-20 is a colourless liquid which accelerates the reaction and curing times of the PU injection resins Sika® Injection-201 CE and Sika® Injection-203, even at low temperatures.

  • With Sika® Injection-AC20 the reaction time of Sika® Injection-201 CE and Sika® Injection-203 can be reduced considerably
  • It is suitable especially for use with both low substrate and low ambient temperatures (5–10 °C)

Application steps

MIXING

Mix Sika® Injection AC-20 with component A of Sika® Injection-201 CE or Sika® Injection-203 immediately before use.

Pour component A of Sika® Injection-201 CE or Sika® Injection-203 into a suitable clean and dry container and add the correct proportion of Sika® Injection AC-20. Stir slowly (max. 250 rpm) for at least 3 min until a homogeneous mixture is achieved.

Inject Sika® Injection-201 CE or Sika® Injection-203 according to their respective product data sheet. The pot life depends on both the material and the ambient temperatures, as well as on the quantity of accelerator added. Lower temperatures will extend, higher temperatures will reduce the reaction time.

CLEANING OF TOOLS

Clean all tools and application equipment with Sika® Colma Cleaner to remove any polyurethane residue immediately after use. Do not leave Sika® Colma Cleaner in the injection pump. Hardened/cured material can only be removed mechanically.
